The stanley fatmax parallel slotted screwdriver with 6.5mm tip size and 150mm blade length represents the heavy duty end of the range, engineered for the most demanding applications. This substantial variant is ideal for large wood screws, heavy construction fixings, and industrial applications where maximum torque transfer and extended reach are both critical requirements. The chrome vanadium steel bar allows exceptionally high torque application whilst reducing the risk of tip breakage, even under extreme load conditions. The handle is moulded directly to the shaft, creating a virtually unbreakable bond that ensures professional grade durability. The soft grip handle provides excellent control and reduces hand fatigue during intensive use, whilst the smooth domed end offers fast, comfortable spinning action. With a large diameter handle specifically designed for higher torque when driving large wood screws, and a parallel tip ideal for driving screws below the material surface, this heavy duty screwdriver delivers uncompromising performance.
